N2 - We have investigated the temperature dependence of unit-cell and structural parameters of ceria (cerium dioxide, CeO2) from room temperature to 1770 K by neutron powder diffraction and the Rietveld method. The unit-cell parameter increases continuously with temperature. It was confirmed that the Debye-Waller factor of oxygen B (O) is larger than that of cerium B (Ce) at any temperature from room temperature to 1770 K. Both B (O) and B (Ce) increase with an increase of temperature.
